ABSTRACT
Sustainability addresses the environmental, economic, and social impacts distributed over the life of a structure. However, in sustainability assessment of a structure, often ordinary events such as normal operation or maintenance actions due to ageing effects are considered and the resilience of the structure to devastating disasters that emphasizes on structural performance and recovery under extreme events is often ignored. Recent experience from natural and man-made hazards, however, highlights that extreme events, particularly earthquake, could affect with a large magnitude, the environmental, economic, and social aspects of our built environment. This study aims to systematically integrate the seismic-resilience into the sustainability assessment of a limited-ductility RC bridge. Sustainability metrics include repair cost, downtime, and environmental impacts and they are computed by consecutive hazard, structural response, damage, and loss analyses in accordance with the performance-based earthquake engineering (PBEE) methodology. Multi-axis substructure testing (MAST) system at Swinburne was used to realistically capture the three-dimensional response of the column, from elastic range to collapse. The data collected from the experiments were then used evaluate the damage-states of the column and quantify the associated seismic-repair sustainability metrics.
